Goes Hilti

The little Canadian Tire hammer-drill I bought just wasn't cutting it... or, well, drilling it... so I bought a bigger, stronger one... a Hilti. Hopefully it will do the job. I'm told it will put 55 holes into 4000 PSI concrete on one battery... granite is harder, but I'm hoping to get 15-20 holes/charge, and with 2 batteries, that should be more than enough for a day's route development.
